Usage Guidelines

Usage Scenario

When the actual total rate for sending packets to the CPU exceeds the set threshold, packets are discarded. This prevents the CPU from being overloaded.

Precautions

In VS mode, this command is supported only by the admin VS.

If the actual total rate for sending packets to the CPU exceeds the configured total rate, subsequent packets will be discarded.

Example

# Set the total rate for sending packets to the CPU to high.
